CARCINOMA OF THE NASOPHARYNX IN YOUNG-PATIENTS

Purpose: To provide an analysis of eighteen cases of adolescent nasopharyngeal carcinoma treated between 1971 and 1989. Methods and Materials: Between 1971 and 1989, 48 cases of nasopharyngeal carcinoma were evaluated at the Medical College of Georgia Hospital and Clinics. Eighteen patients between the ages of 9 and 29 years were treated at the Georgia Radiation Therapy Center. All patients presented for treatment with (AJCC) Stage IV disease. Fifteen patients with lymphoepithelioma and three with squamous cell carcinoma histologies received definitive radiation therapy to a median dose of 64.8 Gy. Males outnumbered females by more than 2:1 and the majority of patients (67%) were black. Nine patients received multiagent adjuvant chemotherapy. Results: Thirteen patients are alive from 7 to 166 months (median 32 months) including three with disease at 17, 24, and 132 months. Overall and disease-free survival at 5 and 10 years were 63% and 54%, respectively. Five patients died from disease; four patients had pulmonary metastases while one had CNS metastasis. Eighty percent of relapses occurred within the first 2 years following treatment. Acute and chronic toxicities were limited, consisting primarily of mucositis and xerostomia. Radiation doses of 65 Gy or more (p = 0.049) and age greater than 20 years (p = 0.005) were positive prognosticators for survival. Adjuvant chemotherapy, race, and sex were not found to be of prognostic value. Disparities in the distribution of patients with lymphoepithelioma and squamous cell histologies and the presentation of advanced regional disease precluded analysis for prognostic significance of histology and nodal status in this series. Conclusion: The results of the present series compare favorably with those published from other institutions. High doses of radiation and a high systemic failure rate continue to be the fundamental obstacles to effective management and enhanced survival for patients with nasopharyngeal carcinoma.
